You can find Krita 6.0.0 on the official blogger.
Today is the simultaneous release of Krita 5.3.0 and Krita 6.0.0!
Depending which version of Qt and KDE Frameworks you build, the same source will result in one of the other. Both versions are almost functionally identical, with 6.0.0 having more Wayland functionality.
But note that since Krita 6 is still considered rather experimental, since it's our first release based on Qt 6, and there were many complicated changes between 5 and 6.
